General prep the usual to get started. pulled the cowl off, disconnected the battery, drained the coolant, and got the coolant reservoir up and out of the way. vent pipe fun the two vent pipes, the 3 way connector, and the heat shield all need to come off to make space. be sure to remove both hoses going to the combi valve. O ring for upper coolant pipe: 058 121 687 (size 31.5 x 3.65) o ring for cts: n 903 168 02 (size: 19.6 x 3.6) o ring for heater core inlet hose: not show in pw etka or my local dealer’s etka. its id (i guess the inner diameter should be around 22 ~ 22.5).

Replacement of coolant pipes from firewall to heater core. the car in question in my daughter's 2014 passat wolfsburg edition (1.8t). we've been trying to track down a slow coolant leak for a year, even the dealership couldn't find it. it finally started getting worse, and i could actually smell coolant in the car. finally tracked the leak down. Ensure a leak free installation. 23x12 secures coolant hose to expansion tank. brand: es#: 516227. mfg#: n90686902. qty: availability: in stock. 10% off msrp $9.99 $8.99. 04 passat 1.8t gls variant manual swapped, 16 a4 s line sport pkg prem , 2017 q5 prem , 07 jetta 2.5, 2015 beetle classic 1.8t previous: 2000 b5 sedan 1.8t, 2013 cc sport dsg, 1998 jetta k2 2.0, 2015 passat tdi selp. Remove the coolant tank cap. 5. attach a hose to the radiator drain leading to a collection container. open the drain valve, allow to drain, and close the valve. 6. once the radiator is drained, it's time to drain the engine block. look under the car and find the water pump drain plug it's a large 19mm bolt.

Check the internet for your car's coolant capacity. my passat was 7.1 liters. pulling the lower radiator hose released about 4 liters, i.e. you need to do a couple of flushes with distilled water until all the old coolant is out (took me 4 drains and refills). then your system is mostly water, i.e. you have to refill with mostly concentrate to. This panel covers the heater core. 4 screws remove it. the core exposed. remove the clamps and pull the lines apart. this was the hardest part. the manual tells you to loosen the 6mm screw that is in between the heater core lines under the hood. it is recessed in a hole between the coolant lines.
